I Patented A r. 23, 1912. 585,764.

To all whom it may concern Be it known that I, J USTUS G. Porrnn, acitizen of the United States, and residing at Brooklyn, in the-county ofKings and State of New York, have invented certain new and usefulImprovements in the Method of Making Imitation Gold-Leaf, of which thefollowing is a specification, such as Will enable those skilled in theart to which it 11 appertains to niake and use the same.

This invention relates to the manufacture of a, composition for makingimitation gold leaf for use in the making of signs, in decorating'booksand for various other purposes 1 and it consists of a new and usefulprocess for producing imitation gold leaf which resembles in allrespects the genuine article, but which is much more durable and muchtougher and which may be used for many 0 of the purposes for whichgenuine gold leaf is employed.

In the practice of my invention I provide a solution of gold bronze,alloy of gold and carlo stripping collodion; said solution being formedby taking approximately eight ounces of the gold bronzeand two andtwothird ounces of the alloy of gold, said articles being in thepowdered form, and these articles are thoroughly mingled in any suitablevessel or receptacle, after which a sufficient amount of the carlostripping collodion is stirred into the product thus formed to form awatery liquid. The carlo stripping collodion above referred to consistsof guncotton, one part; shellac one fourthpart;

glue one fourth part; ether, three parts and alcohol four parts, and thesolution which I employ therefor consists of approximately eight ouncesof gold bronze, and 2 and ounces of alloy of gold, said articles beingin powdered form and combined as above described, after which theguncotton, shellac, glue, ether and alcohol product is stirred thereintoto form a watery liquid. I, then take a sheet of tin and place it on theliquid thus produced and in this operation a thin coating of the liquidadheres to the sheet of tin, and said sheet of tin is then removed fromthe liquid and the said coating is aleither in a natural temperature orin an artificial temperature of preferably not over one hundred degrees.After the llquid coating-has dried on the sheet of tin, it may beremoved therefrom, or peeled off of the sheet of tin in the form of athin sheet or leaf resembling in all respects ordinary gold leaf. Theimitation gold leaf, thus produced, is tougher than the genuine articleand much more durable and may be used for many of the purposes for whichgenuine gold leaf is employed, such as making signs, decorating books,placing the names or titles on books and gildlng the edges of the leavesof books.

When produced, as above described, my imitation gold leaf is not quiteso bright in color as the genuine gold leaf but the difference in thisrespect is very slight; and a different color may be given to theproduct by changing the alloy or substituting another alloy for thealloy of gold specified, as for instance, if a silver colored leaf isdesired an alloy of silver is substituted for the alloy of gold.

Instead of placing the sheet of tin on the liquid as above described andthus producing one leaf of the required product, the sheet of tin may beimmersed in the liquid so that said liquid may adhere. to both sidesthereof and after said sheet of tinhas been removed from the liquid andthe liquid coating allowed to dry on the opposite sides thereof, saidcoating may be removed from both sides of said sheet of tin as will bereadily understood.

Although my imitation gold leaf is not quite so bright in color as thegenuine gold leaf, it is of a brighter color than, and more durable thanany other artificial gold leaf made as far as I know.

Having fully described my invention, what I claim as new and desire tosecure by Letters Patent, is

1. A compositionfor imitation gold leaf consisting of guncotton, onepart; shellac one fourth part; glue one fourth part; ether three parts;and alcohol four parts combined with eight ounces of gold bronze and 2and 5 ounces of alloy of gold. v
